straight, terete, striate, more or less hirsute and glandular-pubes- 
cent; leaves opposite, excepting sometimes some of the small ones 
of the inflorescence, cordate or cuneate at base, ovate, obtuse, 
crenate or crenate-serrate, larger ones 6-7 cm. long and 5-6 cm. 
wide, atomiferous, hirsute-pubescent above, hirsute below, especi- 
ally on the veins, lower surface paler; petioles 2-3 cm. long or 
less, pubescent; inflorescence corymbose on peduncles from the 
axils of the upper leaves or on small branches; peduncles 4-5cm. 
long, glandular hirsute, bractless; involucre 1-1.5 cm. long, cam- 
panulate, the inner bracts linear-lanceolate, acuminate, outer 
bracts ovate-lanceolate, acute, hirsute; flowers in the head 20-30, 
corolla ro-12 mm. long; akenes 1 cm. long, densely silky-villous. 
This plant has been collected by me during every trip made to 
the Cape Region. and now Dr. Purpus has sent much additional 
material, It grows from near sea level at San José del Cabo to 
the summits of the highest mountains. 
The specimens show great variation in characters. The pu- 
bescence of different plants may be slight or densely hispid-hir- 
sute, or of any intermediate grade. The leaf is usually cordate, 
obtuse, but may be ovate-cuneate and acuminate, the outline 
usually crenate-dentate, may be coarsely crenate or sharply ser- 
rate. The inflorescence varies from a corymb of half a dozen 
peduncles from the axils of the upper leaves to one of 15 or more 
heads on branched peduncles. From the characters of B. hebe- 
carpoides it must be a nearly related species. It also somewhat 
resembles B. Hartweg?7. No. 1792, Pringle. 
VIGUIERA DELTOIDEA Gray, var. Tastensis. Leaves 6-10 
cm. long, 4-8 cm. wide, tomentose beneath; inflorescence more 
condensed and of larger flowers than that of the type. The pap- 
pus is very variable: some plants have only two awns from the 
angles of the flattened akene, others bear the typical fruit of the 
species. It is very abundant on the western slope of Sierra El 
Taste. 
ENCELIA RADIANS Brandg., is very abundant in the Sierra de 
la Trinidad of the Cape Region, where it appears very distinct 
from £. farinosa. ‘The type specimen from San Gregorio is the
